' FEB 2.11941 Fig. 7 is a section on the plane denoted by I dotted line l'| on Fig. 8 showing the relative positions of the comb teeth and clamp jaws when they have acted to loop the tie fabrics,

is for simultaneously stitching together the edges with the needle about to enter and. effect the of the covering fabric, to form the tubular outstitching. side, and the interior lining fabric. Fig. 8 is a, side view of what is shown in Fig. 7. The object of the invention contemplates a The apparatus illustrated for practicing the very simple method whereby with a small and method has a bed I of sufflcient length and 10 inexpensive apparatus the stitching of a cover width to receive a tie laid flatwise thereon.

The ends of the bar It are fastened 6 in position to receive the fabrics, and also in to arms l6 that are attached to a shaft I l which full lines one of the clamps and the upper comb is pivotally carried by brackets l8 secured to the that cooperate with the "lower comb for looping back of the bed. This upper comb may be swung the tie fabrics, raised. up and down manually by a handle l9 attached Fig. 6 is a plan view of what is illustrated in to the shaft I! or by any convenient mechanism. PM 5. v when the teeth 3 of the collapsible comb are drawn. together and the upper comb is swung down its teeth IE will pass into the spaces between the teeth 3. Across the upper edges of the comb teeth 3 are notches 20, and across the lower edges of the comb teeth l5 are notches 2!. When; the comb teeth are meshed all of these notches are alignedand form a guide for the stitching needle.

Movable transversely of the bed, near the side to which the collapsible teeth 3 are pushed to bring them together, is a slide 22 to which is attached a long needle 23 with an eye 24 near its point end. when the slide 22 is drawn out to one side, which may be accomplished manually by a handle 25 or by any convenient mechanism, the point of the needle is free from the comb teeth. With the teeth of the comb meshed together the slide may be pushed in so that the needle will pass through and be guided by the aligned notches 20 and 2! in the comb teeth.

A spindle 26 may be set on the bed near the needle slide for a spool of thread, and if desired a cutting blade 21 may be attached to the bed at this end. Across the upper surface of the fingers 3 is a line 28 and also a line 29. These lines may be formed by notching the upper surfaces of the fingers and filling the notches with material having a color that contrasts with the color of the fingers.

In using this apparatus and practicing the method, the fabric 30 that is to be the outside of the tie is folded lengthwise upon itself with the inside out, and placed full length flatwise on the bed over the collapsible comb with its free edges flush with the line 28. The lining fabric 3| is then laid over the free edges of the covering fabric with its rear edge flush with the line 23. The arms with the clamp jaws 3 are turned down so as to lightly bind the covering material and lining between the jaws and the teeth of the collapsible comb. This comb is then collapsed so that the teeth and jaws will slacken the fabric between the teeth. The comb I4 is ..then turned down until its teeth pass between the teeth of the collapsible comb and uniformly loop the slack fabric between the teeth. With the covering and lining held in this relationthe threaded needle is thrust through the loops. As the notches in the upper comb teeth complement the notches in the lower comb teeth and form a guiding passage the needle will not flex but pass straight through the loops. After the threaded needle is thus passed through the loops the thread may be held and the needle drawn back out of the loops,

The thread iscut with ends sufficiently long to be fastened so that the thread will not be withdrawn from the loops when the stitched tie is straightened out. With the needle withdrawn the upper comb is turned up, the teeth of the lower comb and the clamp jaws are separated, and the tie is drawn out so as to flatten the loops. The lining and the covering thus stitched are turned inside out so that the covering fabric will be on the outside and the lining fabric on the ins ide of the seam which stitches together the free edges of the covering.

Bythis method and with this simple apparatus the covering and lining are stitched with one movement of the needle. i

5. The method of stitching ties which comprises folding the finished surface of a covering fabric upon itself, laying a lining fabric over the free edges of the folded covering fabric, gripping said associated covering fabric and lining fabric at intervals from opposite sides, pushing the gripped portions together and producing slack in the intervening portions, transversely stretching said slacked intervening portions and producing loops transversely of the length of the covering and lining fabrics and passing a thread through the stretched loops. 6. An apparatus for stitching ties which comprises a bed, blocks movable transversely toward and from each other longitudinally of said bed.- lost motion links connecting said blocks, comb teeth mounted on and movable transversely of each other with said blocks, a comb pivotally mounted on the bed and having teeth fixed against transverse movement toward and from each other but adapted to be swung down between the teeth of the first mentioned comb when said blocks are moved together, and a needle adapted to be moved longitudinally and passed through openings in said comb teeth.

7. An apparatus for stitching ties which comprises a bed, a set of teeth movable transversely of each other along the bed, means for moving said teeth transversely toward and from each other, a set of teeth immovable transversely-of each other along the bed but pivotallymounted thereon and adapted to be meshed with the first mentioned set of teeth, and a needle adapted to be passed transversely through said teeth when they are meshed.

8. An apparatus for stitching ties which comprises a bed, a set of teeth movable transversely of each other longitudinally along the bed, means when the teeth are meshed form a needle guide, and a needle adapted to be passed transversely through said notches and to be guided by the walls thereof when the teeth are meshed.
